I have a U tube of aquarium line stapled to a board, with a little water in it and I use little balls of cotton in the end near where I plug into the throttle bodies to damp it. Works fine. If you buy a board, air line, some connectors, staples and even cotton balls and all it might cost you $20 bucks. No need for anything else. simple, indestructible, cheap. Only way to go wrong is let the line hit the exhaust, and then you just get more line.

I agree! It was intended as humour and to make but not prove a point. Time moves on. New things come along. That sort of thing.

Not being your average lemming/consumer, I'm not about to throw away my Twin Max and run out and buy a Harmonizer that will not provide me with a smoother running engine.

I'm sure only a lemming would suggest you throw away your Twin Max. But that is not what I said. I never throw out tools even when I have a better one. Just ask my wife!

Accurate? Prove it! Accuracy? What accuracy do you need...its not like you are setting up x millibars at X RPM. You want both cylinders to be the same...thats all.

I agree! It's all about balance. It's funny you should say that though because the Harmonizer allows you to set up you TBs at x millibars at X RPM. And it displays them both very clearly on an easy to read quartz display.

If you really want precision, you'd get one measurement sensor with one hose and a Y splitter with a selector valve and switch left to right to left, etc.

Or two measurement sensors. One for each cylinder. Like a Twin Max or a Harmonizer. But what you do with that signal and how you display it does count for something IMO.

The Twin Max is easy to use and is compact enough to fit in my luggage when I head to Europe to tune my bike there.

Sorry, no advantage there. I've held and used a TwinMax and a Harmonizer. The latter is lighter and smaller. So not sure what your point is.

As for the needle bouncing, you want it to. That is how it works. You're not looking for any particular reading, just a centered position of a quickly swinging needle.No, I don't want it to bounce. My personal preference (and this really is all just personal preference isn't it?) is a steady display that clearly shows where center (in balance) is and not a needle swinging back and forth with a knob to dampen this action.

I'd bet you if I used either to tune an engine, you could not tell the difference. Want to take me up on that bet; I need the money. I was not making any claims about the end result. I am simply saying that in my opinion (worth what it costs you) the Harmonizer is a superior tuning instrument.

Before you tear into other poster's opinions it is always good practice to review the OP's question. And what he was asking was which do we think is the BEST tool. Wouldn't it be easier to just say you like the TwinMax and think it does the job just fine for you? That would answer the question...

Reason: clarity ? Hey one can hope...

I have been down this road myself. I have a Twinmax. Simple to use, my 96 1100 seems to run very well using it, and most critically, it is a tool that is very easy to obtain.

Contrast that to the Harmonizer. Great tool, so everyone claims. I'm sure it is. But...VERY hard to get your hands on. Made by one guy in his garage. He has no email to contact him. You never know when he is going to run a few up. Every time this issue comes up I see that same link posted, like that just solves the problem. Anyone notice that that posting is from June of 2011. We are coming up on 2014, folks. And it is always the same situation: "He's out of them at the moment, but supposed to make some more soon." How could you tell he was out? From the 2011 post? Ridiculous. How do you know when he is going to make any more? You can't contact him. I wish some company, like Twinmax, would buy out his patent, and go into regular production. This is a long rant, but I say that anyone who blithely tells someone like the OP to, "Go buy a Harmonizer," hasn't tried to buy one lately. It appears to be next to impossible. And believe me, I've tried. Now everyone tell me how simple it is to get one, that they had no problem. Okay,... give me his email, give me his phone number, give me his postal address. Then I too can hand over my $140 for this miracle tool.

Yeah I think the last ones shipped last spring. They do come up for sale in the flea market on ADV and other sites now and again. If you follow the thread over on ADV the inventor is going through some personal hardships right now making the production of more product impossible. There are a lot of frustrated would be buyers out there and that is a shame. Again, if you follow the thread you know all this.

But anyway, the OP is just asking for opinions on the best tool out there and I think the Harmonizer is. In the last line of my post I said it's a great tool if you're willing to wait. Perhaps I could have been more clear that they are not available right now and Grok has not been regularly updating his situation. But the first post in his thread is pretty clear.

Subscribing to the thread is the best way to know when and if they become available again. I just got lucky I guess. Heard about it, read about it, ordered one and got it right away.

If not twinmax?

What is a TecMate TS-111 CarbMate Synchronizer? Anyone use it? Looks to sync two vacuum lines. Available from big internet marketer (or a river in S America?) with 15 very good reviews. Anyone have experience? $95 shipped and no analog dial. See it at http://www.amazon.com/s/ref=nb_sb_ss...e+%2Caps%2C374

If you must make a mistake, make a new one each time.

Well, I have to apologize to the group. The most recent post on that 79 page thread in ADV Rider is actually from 10-5-13. Looks like a lot of people have been following it for two years in hopes of buying one. Of course at the end of it all, the result is the same: none available at this time. And I agree, the OP wanted to know the best tool, it apparently is the Harmonizer. Not much debate from anyone, including me, on that point. I guess this guy Grok has some personal issues going on that don't seem to be getting resolved very quickly. Myself, I wasted two+ riding seasons restoring my "dream" airhead that I planned to ride, only to quickly sell it. Now I just enjoy actually riding my trusty oilhead, not constantly waiting for parts or special tools. If a tool isn't available, I move on, find something that is out there, and which works reasonably well. I'm just saying that the OP may want to do the same.

Yup, I'm using it on my R90/6, dead simple to use and I'm happy with it. YMMV
